PREPARATION-APPLICATION

Check that the substrate is clean of loose material, dust, etc. Using an electric low speed drill, mix well a 25kg bag with approximately 6 liters of clean water until you get a homogenous mass without sticky lumps. Leave the mixture for 5-10 minutes to to mature and mix again for a while. As an adhesive, apply the GNK20W, either across the surface of the insulation board with a notched trowel, or around the board and selectively in the center with a trowel, so that the adhesive covers at least 40% of insulation board surface. Placement of the insulating boards must start from the bottom of the wall upwards, crosswise and with no gaps. As reinforced mortar, apply the material with a notched trowel in 2-3mm thickness. In this layer place the fiberglass mesh and dip the mesh in the layer using a smooth spatula. The strips of the mesh should overlap by 10cm approx. At the end polish the surface, while simultaneously remove excess mortar. The pot life of the finished mixture is 1-3 hours depending on the ambient temperature and the season time.
